CVE-2025-6582 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Best Salon Management System, specifically within the /edit-customer-detailed.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without requiring user interaction or prior authentication, injecting malicious SQL code that alters the intended database query logic. This can lead to unauthorized access to sensitive customer data, modification or deletion of records, and potentially full compromise of the underlying database. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 base score is 5.3, indicating a medium severity level, reflecting the ease of remote exploitation but limited scope and impact on confidentiality, integrity, and availability. The attack vector is network-based with low attack complexity and no privileges or user interaction required, but the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability affects only version 1.0 of the product, which is a niche salon management system typically used by small to medium-sized businesses to manage customer appointments, records, and related operations.

For European organizations using the SourceCodester Best Salon Management System 1.0, this vulnerability poses a risk of unauthorized data exposure and manipulation. Given that salon management systems handle personal customer data, including contact details and appointment histories, exploitation could lead to breaches of personal data privacy under GDPR regulations, resulting in legal and financial consequences. Additionally, data integrity issues could disrupt business operations, causing loss of customer trust and operational downtime. However, the impact is somewhat limited by the product's niche market and the absence of known active exploits. Organizations relying on this system should be aware that attackers could leverage this vulnerability to escalate attacks within their network if the system is connected to broader IT infrastructure. The medium severity rating suggests a moderate risk, but the potential for data breaches and regulatory non-compliance elevates the importance of addressing this issue promptly.

To mitigate this vulnerability, organizations should first verify if they are running version 1.0 of the SourceCodester Best Salon Management System and plan an immediate upgrade or patch application once available from the vendor. In the absence of an official patch, implement input validation and parameterized queries or prepared statements in the /edit-customer-detailed.php script to sanitize the 'editid' parameter and prevent SQL injection. Network-level controls such as web application firewalls (WAFs) can be configured to detect and block SQL injection patterns targeting this parameter. Restrict access to the management system to trusted internal networks or VPNs to reduce exposure. Conduct regular security audits and database monitoring to detect unusual query patterns or unauthorized data access. Additionally, ensure that database accounts used by the application have the least privileges necessary to limit the impact of any successful injection. Finally, maintain comprehensive backups of customer data to enable recovery in case of data tampering.
